ObjectiveTo reveal the mechanism of Zuogui Jiangtang Jieyu prescription against damage to hippocampal synaptic microenvironment via suppressing glutamate receptor 2 (GluR2)/Parkin signal-mediated mitophagy in rats with diabetes-related depression (DD). MethodsEighty male SD rats underwent adaptive feeding for 5 days before the study. Ten rats were randomly assigned to the normal group. The model of DD rats was established with the rest by 2-week high-fat diet + streptozotocin (STZ) tail intravenous injection + 28 days of chronic unpredictable mild stress (CUMS) combined with isolation. The rats were randomly divided into a normal group, a model group, a GluR2 blocker group (5 μg·kg-1), a GluR2 agonist group (10 μg·kg-1), a metformin + fluoxetine group (0.18 g·kg-1 metformin + 1.8 mg·kg-1 fluoxetine), and high- and low-dose Zuogui Jiangtang Jieyu prescription groups (20.52 and 10.26 g·kg-1, respectively). The rats in the GluR2 blocker group and the GluR2 agonist group were continuously injected with CNQX and Cl-HIBO in the dentate gyrus of the hippocampus once a week starting from stress modeling, respectively, while the metformin + fluoxetine group and the high- and low-dose Zuogui Jiangtang Jieyu prescription groups were continuously given intragastric administration for 28 d at the same time of stress modeling. Depression-like behavior was evaluated by open field and forced swimming experiments. The levels of serum insulin and adenosine triphosphate (ATP) in hippocampus were detected by biochemical analysis. The levels of 5-hydroxytryptamine (5-HT) and dopamine (DA) in hippocampus were detected by enzyme-linked immunosorbent assay (ELISA). The autophagosomes of hippocampal neurons were observed by transmission electron microscopy. The morphology and structure of dendrites and spines of hippocampal neurons were evaluated by Golgi staining. Western blot detected the expression levels of GluR2 and Parkin proteins in hippocampus. The expression levels of GluR2, Parkin, regulating synaptic membrane exocytosis protein 3 (RIMS3), and postsynaptic density protein 95 (PSD95) in the dentate gyrus of the hippocampus were detected by immunofluorescence. ResultsCompared with the normal group, the model group exhibited reduced total activity distance in the open field and increased immobility time in forced swimming (P<0.01), lowered levels of serum insulin and ATP, 5-HT, and DA in hippocampus (P<0.01), increased autophagosomes of hippocampal neurons, significantly damaged morphology and structure of dendrites and spines of hippocampal neurons, decreased expression levels of GluR2, RIMS3, and PSD95 in hippocampus, and an increased Parkin expression level (P<0.05, P<0.01). Compared with the model group, the GluR2 blocker group and the GluR2 agonist group showed aggravation and alleviation of the above abnormal changes, respectively (P<0.05, P<0.01). The above depression-like behavior was significantly improved in the high- and low-dose Zuogui Jiangtang Jieyu prescription groups to different degrees. Specifically, the two groups saw elevated levels of serum insulin and ATP, 5-HT, and DA in hippocampus (P<0.05, P<0.01), restrained increase in autophagosomes and damage to morphology and structure of dendrites and spines of hippocampal neurons, up-regulated protein expression levels of GluR2, RIMS3, and PSD95, and down-regulated Parkin expression level (P<0.05, P<0.01). ConclusionZuogui Jiangtong Jieyu prescription can ameliorate the mitophagy-mediated damage to hippocampal synaptic microenvironment in DD rats, the mechanism of which might be related to the regulation of GluR2/Parkin signaling pathway.

ObjectiveTo explore and verify the key pathway of Zuogui Jiangtang Jieyu prescription in the treatment of diabetes with depression by means of gene set enrichment analysis (GSEA) and short time-series expression miner (STEM). MethodSD rats were randomly divided into six groups, including a normal group, a model group, high, medium, and low dose groups of Zuogui Jiangtang Jieyu prescription, and a positive drug group. The model of diabetes with depression was established by high-fat feeding, streptozotocin (STZ) injection, and chronic mild unpredictable stress. The high, medium, and low dose groups of Zuogui Jiangtang Jieyu prescription were orally administered at 20.52, 10.26, and 5.13 g·kg-1 respectively. The positive drug group was orally administered 0.18 g·kg-1 metformin and 1.8 g·kg-1 fluoxetine. The rats in the normal group and model group were administered with an equal volume of distilled water. After 28 days, the animals were tested for depressive-like behaviors and cognitive function using the forced swimming test and Morris water maze. Fasting blood glucose was measured using blood glucose test strips. Cholesterol and triglyceride levels were measured using enzyme-linked immunosorbent assay (ELISA). Three hippocampus samples were randomly selected from the normal group, the model group, the high dose group of Zuogui Jiangtang Jieyu prescription for high-throughput transcriptome sequencing. Differential gene analysis, GSEA analysis, and STEM analysis were used to screen the key pathways and target genes of Zuogui Jiangtang Jieyu prescription in the treatment of diabetes with depression. Key target genes were validated using real-time fluorescence quantitative PCR (Real-time PCR). The expression of the signal protein mediated by the target genes was detected by Western blot. ResultCompared with the results in the normal group, the fasting blood glucose, cholesterol, and triglyceride levels in the model group were significantly increased (P<0.01). Moreover, the immobility time in the forced swimming test was significantly increased, while the time to climb the platform was significantly prolonged, and the search distance in the target quadrant was significantly reduced in the Morris water maze test (P<0.05,P<0.01). Compared with the model group, the high dose of Zuogui Jiangtang Jieyu prescription significantly reduced the levels of blood glucose, cholesterol, and triglycerides in rats with diabetes with depression (P<0.05,P<0.01), reduced the immobility time in the forced swimming test, shortened the stage time in the Morris water maze test, and increased the search distance ratio in the target area (P<0.05,P<0.01). Transcriptome sequencing differential analysis showed that the normal group had 1 366 differentially expressed genes compared to the model group, while the model group had 1 149 differentially expressed genes compared to the high dose group of Zuogui Jiangtang Jieyu prescription, with 581 intersecting genes. The GSEA results showed that there were 9 sets of differentially expressed genes between the normal group and the model group, and 43 sets of differentially expressed genes between the model group and the high dose group of Zuogui Jiangtang Jieyu prescription, with 7 intersecting gene sets. STEM analysis showed that according to the analysis order of the normal group, model group, and high dose group of Zuogui Jiangtang Jieyu prescription, two significantly different trend clustering groups were obtained. One key gene set for axonal guidance, as well as key target signal elements Sema3c, Sema7a, Robo3, Epha8, and Epha7, were identified through synthesizing the three analysis results. Real-time PCR validated that compared with the results in the normal group, the mRNA expression of Robo3, Sema7a, and Epha7 in the hippocampus of the model rats was significantly reduced (P<0.05, P<0.01). Compared with the model group, the high dose of Zuogui Jiangtang Jieyu prescription significantly increased the mRNA expression of Robo3, Sema7a, and Epha7 (P<0.05, P<0.01). Western blot results showed that compared with the results in the normal group, the Sema7a, ITGB1, and FAK protein expression in the hippocampus of the model group was significantly reduced (P<0.01). Compared with the model group, the high dose of Zuogui Jiangtang Jieyu prescription significantly increased the protein expression of Sema7a, ITGB1, and FAK in the hippocampus (P<0.05,P<0.01). ConclusionZuogui Jiangtang Jieyu prescription may treat diabetes with depression by regulating axonal guidance based on the Sema7a/ITGB1 signaling pathway.

ObjectiveTo explore the potential mechanism of Zuogui Jiangtang Jieyu Formula (左归降糖解郁方, ZJJF) for diabetic rats with depression. MethodsSixty rats were randomly divided into normal group, model group, wingless MMTV integration site family member 5a (Wnt5a) agonist group, ZJJF group, and ZJJF plus Wnt5a inhibitor group, with 12 rats in each group. Except for the normal group, the rats were fed with high-fat chow, streptozotocin injection, and chronic mild unpredictable stress combination, to establish model of diabetes mellitus complicated with depression. After successful modelling, rats in the Wnt5a agonist group were given bilateral hippocampal stereotactic injections of Wnt5a agonist Foxy-5 with 5 μl each for 7 consecutive days; rats in ZJJF group were given 20.52 g/(kg·d) of ZJJF by gavage; rats in ZJJF plus Wnt5a inhibitor group were given the drug by gavage, and bilateral hippocampal stereotactic injections of Wnt5a inhibitors Box5, with the same dosage and injection method as above. The normal group and model group were given 10 ml/(kg·d) of normal saline by gavage. All groups were gavaged for 4 consecutive weeks. At the end of the intervention, the depression-like behaviour of rats was evaluated using the forced swimming experiment (immobility time) and the absent field experiment (number of activities); the blood glucose and insulin levels of rats were measured and the insulin resistance index was calculated; the dendritic morphology of dentate gyrus neurons in the hippocampus was observed using Golgi staining; the level of dentate gyrus neuron proliferation was measured using 5-bromodeoxyuracil nucleoside (Brdu) injection and immunofluorescence; RT-qPCR and Western blot were used to detect the mRNA and protein expression of Wnt5a, Ras homologue genomic member A (RhoA) and Rho homologue-associated coiled-coil protein kinase 1 (ROCK1) in the dentate gyrus. ResultsCompared with the normal group, rats in the model group had significantly higher blood glucose, insulin and insulin resistance indices, longer immobility time, fewer activities, lower Brdu integral optical density values and Wnt5a, RhoA, ROCK1 protein and mRNA expression in the dentate gyrus of the hippocampus (P<0.05 or P< 0.01); the dendritic branches of rat hippocampal dentate gyrus neurons could be seen to be significantly reduced or broken, and their length shortened. Compared with the model group, the blood glucose, insulin and insulin resistance indices of rats in ZJJF group and the ZJJF plus Wnt5a inhibitor group significantly reduced (P<0.05 or P<0.01); the immobility time of rats in the Wnt5a agonist group and ZJJF group was significantly shortened, the number of activities increased, the Brdu integral optical density values elevated, and the Wnt5a, RhoA, ROCK1 protein and mRNA expression elevated (P<0.05 or P<0.01), and the number of dendritic branches of hippocampal dentate gyrus neurons significantly increased, the length lengthened, and the complexity of dendrites increased. Compared with the Wnt5a agonist group, rats in the ZJJF group showed significant decrease in blood glucose, insulin and insulin resistance indices, prolongation of immobilisation time, reduction in the number of activities, and reduction in the Brdu integral optical density value; except for the Wnt5a mRNA in ZJJF group, Wnt5a, RhoA, ROCK1 protein and mRNA expression reduced in both ZJJF group and ZJJF plus Wnt5a inhibitor group (P<0.05 or P<0.01). Compared with ZJJF group, Wnt5a, RhoA, ROCK1 protein and mRNA expression were reduced in ZJJF plus Wnt5a inhibitor group (P<0.05 or P<0.01). ConclusionZJJF can improve hyperglycemia and depressive-like behaviours in rat models of diabetes with depression, and its antidepressant effects may be related to the activation of hippocampal Wnt5a/RhoA signaling and promotion of dentate gyrus neuron dendritic growth.

Objective:To translate the Dysfunctional Beliefs and Attitudes about Sleep Scale for Cancer Patients (C-DBAS-14) into Chinese and test its reliability and validity.Methods:The Korean version of C-DBAS-14 was translated, back-translated, and culturally adapted into Chinese based on Brislin's translation model, forming the Chinese version of C-DBAS-14. From October 2022 to May 2023, 361 hospitalized cancer patients at the First Affiliated Hospital of Anhui Medical University were selected as research objects by convenient sampling method. They were surveyed using a general information questionnaire, the Chinese version of C-DBAS-14, the Insomnia Severity Index (ISI), and the Hospital Anxiety and Depression Scale (HADS) to evaluate the reliability and validity of the scale. The scale's item analysis was based on correlation coefficients and critical ratio values; structural validity, content validity, and convergent validity were used to evaluate the scale's validity; Cronbach's α coefficient and intraclass correlation coefficient were used to assess its reliability.Results:A total of 361 questionnaires were distributed, 356 were effectively returned, with an effective response rate of 98.6% (356/361). The Chinese version of C-DBAS-14 contained 14 items across four dimensions. The scale-level content validity index was 0.976, and the item-level content validity index ranged from 0.833 to 1.000. Totally four common factors were extracted in exploratory factor analysis, explaining 78.8% of the total variance. Confirmatory factor analysis showed a Chi-square/degrees of freedom ratio of 1.286, comparative fit index of 0.991, goodness of fit index of 0.945, incremental fit index of 0.991, Tucker-Lewis index of 0.988, and root mean square error of approximation of 0.036. The total Cronbach's α coefficient of the scale was 0.874, and the intraclass correlation coefficient was 0.863. The C-DBAS-14 score was negatively correlated with the ISI and HADS scores ( r=-0.734, -0.639; P<0.01) . Conclusions:The Chinese version of C-DBAS-14 has good reliability and validity and can be used as an assessment tool for irrational sleep beliefs in Chinese cancer patients.

OBJECTIVE:
To investigate the effect of Zuogui Jiangtang Jieyu Decoction (ZJJ) on Shh signaling and self-renewal of neural stem cells in the hippocampal dentate gyrus of diabetic rats with depression.
METHODS:
Diabetic rat models with depression were randomly divided into model group, positive drug (metformin + fluoxetine) group, and low-, medium-, and high-dose ZJJ groups (n=16), with normal SD rats as the control group. The positive drugs and ZJJ were administered by gavage, and the rats in the control and model groups were given distilled water. After the treatment, blood glucose level was detected using test strips, and behavioral changes of the rats were assessed by forced swimming test and water maze test. ELISA was used to examine the serum level of leptin; The expressions of nestin and Brdu proteins in the dentate gyrus of the rats were detected using immunofluorescence assay, and the expressions of self-renewal marker proteins and Shh signaling proteins were detected using Western blotting.
RESULTS:
The diabetic rats with depression showed significantly increased levels of blood glucose and leptin (P < 0.01) and prolonged immobility time in forced swimming test (P < 0.01) and increased stage climbing time with reduced stage seeking time and stage crossings in water maze test (P < 0.01). The expressions of nestin and Brdu in the dentate gyrus, the expressions of cyclin D1, SOX2, Shh, Ptch1, Smo in the hippocampus and the nuclear expression of Gli-1 were decreased (P < 0.01) while hippocampal Gli-3 expression was increased significantly (P < 0.01) in the rat models. Treatment of rat models with high-dose ZJJ significantly reduced the blood glucose (P < 0.01) and leptin level (P < 0.05) and improved their performance in behavioral tests (P < 0.01). The treatment also obviously increased the expressions of nestin, Brdu, cyclin D1, SOX2, Shh, Ptch1, and Smo and the nuclear expression of Gli-1 in the dentate gyrus (P < 0.01) and reduced hippocampal expression of Gli-3 (P < 0.05) in the rat models.
CONCLUSION
ZJJ can significantly improve the self-renewal ability of neural stem cells and activate Shh signaling in dentate gyrus of diabetic rats with depression.

Objective:To study the effects of Zuogui Pills on the expressions of miR-133b-3p and RhoA in osteoclasts of postmenopausal osteoporosis rats; To discuss its potential mechanism.Methods:SD female rats were randomly divided into normal group, model group, sham-operation group, and Zuogui Pills group using a random number table method, with 6 rats in each group. The model group and Zuogui Pills group were treated with oophorectomy to construct a rat model of osteoporosis. Zuogui Pills group was orally administered with Zuogui Pills decoction at a concentration of 10 g/kg for 12 consecutive weeks. Colorimetric method was used to measure the serum calcium and phosphorus levels of rats, and ELISA method was used to detect ALP levels. Bone density meter was used to measure the bone density of the femurs of rats in each group. The osteoclast of each group were cultured, and the expressions of RANKL and RUNX2 protein were detected by Western blot. MiRNA sequencing and differential expression analysis were performed on bone tissues of rats. Osteoclasts were treated with miR-133b-3p mimic and its negative control. The cell proliferation activity of osteoclasts was detected by cell counting kit-8 (CCK-8). The osteoclast differentiation activity was detected by the tartrate-resistant acid phosphatase staining. The dual-luciferase reporter assay was used to detect the relationship between miR-133b-3p and RhoA. The "rescue" experiment of miR-133b-3p mimic and RhoA co-expression were used to study the molecular regulatory mechanism of Zuogui Pills on osteoclast activity.Results:Compared with the model group, the bone mineral density of Zuogui Pills group significantly increased ( P<0.05, P<0.01), the levels of calcium and phosphorus in serum increased, the level of alkaline phosphatase ALP decreased ( P<0.05), the expression of RANKL protein decreased, and the expression of RUNX2 protein increased. Sequencing results showed that rno-miR-133b-3p was down-regulated in osteoclasts of postmenopausa osteoporosis rats treated with Zuogui Pills with the maximum difference ( P<0.01). Q-PCR results showed that the expression of miR-133b-3p in osteoclasts of Zuogui Pills group was significantly lower than that of the model group. The upregulation of miR-133b-3p could significantly promote the cell proliferation and differentiation of osteoclasts. RhoA overexpression could reverse the excessive proliferation and differentiation of osteoclasts caused by miR-133b-3p overexpression. Conclusions:RhoA is the target gene regulated by miR-133b-3p. Zuogui Pills can inhibit the activity of osteoclasts by regulating miR-133b-3p/RhoA axis, relieving the symptoms of osteoporosis.
